Abstract

Communication networks and associated methods and systems are disclosed that provide per-session dynamic charging caps. For a session, the communication network includes a network element adapted to serve the session, a charging system, and a subscriber server adapted to store charging criteria defined for a party to the session. In operation, the charging system receives one or more charging request messages from the network element. Responsive to a charging request message, the charging system identifies the charging criteria defined for the party as stored in the subscriber server, and determines a dynamic charging cap for the session based on the charging criteria. A charging cap is a limited or maximum amount of time and/or money that is charged for an individual session. The charging system then limits the charging for the session based on the dynamic charging cap.

Claims

1. A communication network adapted to provide a per-session charging cap for sessions, the communication network comprising:

a subscriber server adapted to store charging criteria defined for a party; and

a charging system adapted to receive at least one charging request message from a network element that is serving a session involving the party, to identify the charging criteria defined for the party as stored in the subscriber server, to determine a dynamic charging cap for the session based on the charging criteria, and to limit charging for the session based on the dynamic charging cap.

2. The communication network of claim 1 wherein the charging system is further adapted to:

determine a dynamic stepped rating for the session based on the charging criteria defined for the party; and

charge for the session based on the dynamic stepped rating as limited by the dynamic charging cap.

3. The communication network of claim 1 further comprising the network element adapted to:

determine that the dynamic charging cap is reached during the session; and

notify the party when the dynamic charging cap is reached.

4. The communication network of claim 1 wherein the charging system is further adapted to determine the dynamic charging cap for the session based on the charging criteria and information on another party to the session.

5. The communication network of claim 1 wherein the charging system is further adapted to determine the dynamic charging cap for the session based on the charging criteria and the media type for the session.

6. The communication network of claim 1 wherein the charging system is further adapted to determine the dynamic charging cap for the session based on the charging criteria and the time of day or day of the week for the session.

7. The communication network of claim 1 wherein the charging system is further adapted to determine the dynamic charging cap for the session based on the charging criteria and a service plan subscribed to by the party.

8. A method of providing a per-session charging cap for sessions in a communication network, the method comprising:

receiving at least one charging request message from a network element that is serving a session involving a party;

identifying the charging criteria defined for the party;

determining a dynamic charging cap for the session based on the charging criteria; and

limiting charging for the session based on the dynamic charging cap.

9. The method of claim 8 further comprising:

determining a dynamic stepped rating for the session based on the charging criteria defined for the party; and

charging for the session based on the dynamic stepped rating as limited by the dynamic charging cap.

10. The method of claim 8 further comprising:

determining that the dynamic charging cap is reached during the session; and

notifying the party when the dynamic charging cap is reached.

11. The method of claim 8 wherein determining a dynamic charging cap for the session based on the charging criteria comprises:

determining the dynamic charging cap for the session based on the charging criteria and information on another party to the session.

12. The method of claim 8 wherein determining a dynamic charging cap for the session based on the charging criteria comprising:

determining the dynamic charging cap for the session based on the charging criteria and the media type for the session.

13. The method of claim 8 wherein determining a dynamic charging cap for the session based on the charging criteria comprises:

determining the dynamic charging cap for the session based on the charging criteria and the time of day or day of the week for the session.

14. The method of claim 8 wherein determining a dynamic charging cap for the session based on the charging criteria comprises:

determining the dynamic charging cap for the session based on the charging criteria and a service plan subscribed to by the party.

15. A method of providing a per-session charging cap for postpaid sessions in a communication network, the method comprising:

receiving charging request messages from a network element that is serving a postpaid session involving a party;

calculating a total duration for the postpaid session based on the charging request messages;

identifying charging criteria defined for the party;

determining a dynamic charging cap for the postpaid session based on the charging criteria;

determining a rating for the postpaid session;

determining a charge for the postpaid session based on the rating and the total duration for the postpaid session; and

limiting the charge for the postpaid session based on the dynamic charging cap.

16. The method of claim 15 further comprising:

determining a dynamic stepped rating for the postpaid session based on the charging criteria defined for the party; and

determining a charge for the postpaid session based on the dynamic stepped rating and the total duration for the postpaid session.

17. The method of claim 15 further comprising:

determining that the dynamic charging cap is reached during the postpaid session; and

notifying the party when the dynamic charging cap is reached.

18. A method of providing a per-session charging cap for prepaid sessions in a communication network, the method comprising:

receiving a charging request message from a network element that is serving a prepaid session involving a party;

identifying a prepaid account for the party;

identifying charging criteria defined for the party;

determining a dynamic charging cap for the prepaid session based on the charging criteria;

determining a rating for the prepaid session;

allocating a credit quota for the prepaid session based on the rating, the prepaid account balance for the party, and the charging cap; and

transmitting a charging answer message to the network element indicating the granted credit quota for the prepaid session.

19. The method of claim 18 further comprising:

receiving another charging request message from the network element;

allocating another credit quota for the prepaid session based on the rating, the prepaid account balance for the party, and the charging cap; and

transmitting another charging answer message to the network element indicating the granted credit quota for the prepaid session.

20. The method of claim 18 further comprising:

determining a dynamic stepped rating for the prepaid session based on the charging criteria defined for the party.
